What is CSS Animation Generator?

Create CSS keyframe animations visually — no hand-coding needed. Set up keyframes, pick timing functions, tweak duration and delays, then copy the CSS straight into your project. Works great for buttons, loaders, hover effects, and page transitions.

Pick from a library of over forty ready-made animations grouped into Fade, Slide, Zoom, Rotate, Bounce, Attention, Exit and Loaders, or build your own from scratch. Each keyframe lets you set opacity, scale, rotation, translate X and Y, skew X and Y, blur, border radius, box shadow and background colour. Already have a @keyframes block? Paste it into the import dialog and the visual editor will reconstruct every step. Pause the preview and drag the red scrubber to inspect any mid-animation frame, then export plain @keyframes CSS ready to drop into any stylesheet.

How to use

1. Choose an animation preset (fade, slide, bounce, rotate) or start from scratch by adding keyframes on the timeline.
2. Adjust properties at each keyframe — transform, opacity, color, scale — and fine-tune the easing curve, duration, and iteration count.
3. Preview the animation in real-time, then copy the generated CSS @keyframes code or download it as a .css file.

When to use

• Adding entrance animations to hero sections, modals, or cards when a page loads.
• Designing micro-interactions for buttons, like a subtle scale on hover or a shake on form errors.
• Prototyping loading spinners and skeleton states before wiring them into a framework.

Result

A frontend developer needs a smooth entrance animation for cards on a portfolio page. They set up a 0.6s ease-out animation that fades in from 20px below, copy the CSS, and apply it with a staggered delay per card.

FAQ

What's the difference between CSS animations and CSS transitions?

Transitions go from state A to state B once on a trigger such as hover, focus, or a class change. Animations follow a @keyframes rule with as many in-between steps as you want, can loop, and start on page load without user input.

Why does my animation play once and then disappear?

The element returns to its base styles when the animation ends. Set animation-fill-mode to forwards so the final keyframe's values stick around, or to both if you also need the first keyframe to apply during any delay.

Which easing should I pick for a natural feel?

For entrances, ease-out slows down at the finish so motion feels settled. For exits, ease-in does the opposite. cubic-bezier(0.34, 1.56, 0.64, 1) gives a slight overshoot that reads as playful without being silly.

Will these animations work on older browsers?

@keyframes is supported in every browser released after 2013, no vendor prefix needed. If you target IE 10 or below you would need the -webkit- prefix, but that is well below modern usage thresholds and rarely worth the extra CSS.

How do I make an animation loop forever?

Set iteration count to infinite. Pair it with alternate direction so the animation reverses on every other cycle and you get a smooth back-and-forth, which works well for pulse and shake effects instead of a hard jump back to the start.
